Practical Cryptography in Python : Learning Correct Cryptography by Example
Develop a greater intuition for the proper use of cryptography.This book teaches the basics of writing cryptographic algorithms in Python, demystifies cryptographic internals, and demonstrates common ways cryptography is used incorrectly. Cryptography is the lifeblood of the digital world’s security infrastructure.From governments around the world to the average consumer, most communications are protected in some form or another by cryptography.These days, even Google searches are encrypted. Despite its ubiquity, cryptography is easy to misconfigure, misuse, and misunderstand. Developers building cryptographic operations into their applications are not typically experts in the subject, and may not fully grasp the implication of different algorithms, modes, and other parameters.The concepts in this book are largely taught by example, including incorrect uses of cryptography and how "bad" cryptography can be broken.By digging into the guts of cryptography, you can experience what works, what doesn't, and why. What You’ll LearnUnderstand where cryptography is used, why, and how it gets misusedKnow what secure hashing is used for and its basic propertiesGet up to speed on algorithms and modes for block ciphers such as AES, and see how bad configurations breakUse message integrity and/or digital signatures to protect messagesUtilize modern symmetric ciphers such as AES-GCM and CHACHAPractice the basics of public key cryptography, including ECDSA signaturesDiscover how RSA encryption can be broken if insecure padding is usedEmploy TLS connections for secure communicationsFind out how certificates work and modern improvements such as certificate pinning and certificate transparency (CT) logsWho This Book Is ForIT administrators and software developers familiar with Python.Although readers may have some knowledge of cryptography, the book assumes that the reader is starting from scratch.

Information-theoretic Cryptography
This book offers a mathematical foundation for modern cryptography.It is primarily intended as an introduction for graduate students.Readers should have basic knowledge of probability theory, but familiarity with computational complexity is not required.Starting from Shannon's classic result on secret key cryptography, fundamental topics of cryptography, such as secret key agreement, authentication, secret sharing, and secure computation, are covered.Particular attention is drawn to how correlated randomness can be used to construct cryptographic primitives.To evaluate the efficiency of such constructions, information-theoretic tools, such as smooth min/max entropies and information spectrum, are developed.The broad coverage means the book will also be useful to experts as well as students in cryptography as a reference for information-theoretic concepts and tools.
